[0006] The effect achieved by the above components is as follows: when it is necessary to install the mechanical mounting shaft, the operator moves the mechanical mounting shaft and inserts it into the inside of the mounting ring. Then, the fixing device fixes the mechanical mounting shaft in the mounting ring. Finally, the operator moves the U-shaped frame, which moves with the guide rod in the guide tube. When the mounting ring moves to the appropriate height, the operator fixes the height of the mounting ring by adjusting the device.
[0007] Preferably, the fixing device includes a gear ring rotatably connected to the arc surface of a mounting ring. Four toothed plates slide through the surface of the mounting ring, and the four toothed plates are circumferentially distributed.

The main gear is rotatably connected to the mounting ring via a support plate, wherein the main gear meshes with the gear ring. The driven gear is fixedly connected to one side of the main gear, and the driven gear meshes with the toothed plates. The screw is threadedly connected to one arm of a U-shaped frame. A movable plate is fixedly connected to the arc surface of the gear ring inside the U-shaped frame, wherein one end of the screw abuts against the movable plate. A spring is fixedly connected to one side of the movable plate, wherein the other end of the spring is fixedly connected to the U-shaped frame.
[0008] The aforementioned components achieve the following effect: When the mechanical mounting shaft needs to be fixed, the operator rotates the screw, which presses against the moving plate. The moving plate rotates along with the gear ring, causing the spring to deform. The gear ring, along with the main gear and the driven gear, rotates together. The driven gear moves the gear plate and the clamping plate. The four arc-shaped clamping plates together press against the mechanical mounting shaft, thus achieving the effect of fixing the mechanical mounting shaft.

[0016] The effect achieved by the above components is as follows: after the mounting ring is moved to the appropriate height, the operator rotates the bolt on the L-shaped plate, and the bolt presses against the rectangular plate of the guide rod, thereby fixing the guide rod. The auxiliary device facilitates the operator to adjust the height of the mounting ring, thus improving the practicality of the mechanical adjustment frame.
[0017] Preferably, a pull rope is fixedly connected to one side of the bolt, wherein one end of the pull rope is fixedly connected to the L-shaped plate.
[0018] The effect achieved by the above components is that by setting up a pull rope, the maximum displacement of the bolt is limited, thus preventing the bolt from falling off when not in use.

[0022] When it is necessary to fix the mechanical mounting shaft, the operator rotates the screw, which presses against the moving plate. The moving plate rotates along with the gear ring, causing the spring to deform. The gear ring, along with the main gear and the driven gear, rotates together. The driven gear moves the gear plate and the clamping plate. The four arc-shaped clamping plates together press against the mechanical mounting shaft, achieving the effect of fixing the mechanical mounting shaft. When it is necessary to disassemble the mechanical mounting shaft, the operator rotates the screw in the opposite direction. The screw releases the pressure on the moving plate. At this time, under the action of the spring's return force, the moving plate rotates in the opposite direction, and the clamping plates release the pressure on the mechanical mounting shaft. Finally, the operator removes the mechanical mounting shaft. The fixing device allows for easy fixing of mechanical mounting shafts of different widths with the mounting ring, improving the practicality of the mechanical adjustment frame.

[0029] Reference Figure 1-5 As shown, this embodiment discloses a mechanical adjustment frame, including a base 1 and an auxiliary device 7. The base 1 is detachably screwed and mounted on the frame to provide overall support. A guide tube 2 is fixedly connected to the upper surface of the base 1, and a guide rod 3 is slidably connected inside the guide tube 2. The auxiliary device 7 can fix the guide rod 3 and the guide tube 2. A U-shaped frame 4 is installed at one end of the guide rod 3, and the two arms of the U-shaped frame 4 are fixedly connected to the same mounting ring 5, wherein the mounting ring 5 is sleeved on the surface of the mechanical mounting shaft. A fixing device 6 is installed on the surface of the mounting ring 5, wherein the fixing device 6 can fix the mechanical mounting shaft in the mounting ring 5. When the mechanical mounting shaft needs to be installed, the operator moves the mechanical mounting shaft and inserts it into the interior of the mounting ring 5. Then, the fixing device 6 fixes the mechanical mounting shaft in the mounting ring 5. Finally, the operator moves the U-shaped frame 4, which moves the guide rod 3 in the guide tube 2. When the mounting ring 5 moves to a suitable height, the operator fixes the height of the mounting ring 5 using the adjustment device.
[0030] Reference Figure 1-5As shown, the fixing device 6 includes a toothed ring 61, which is rotatably connected to the arc surface of the mounting ring 5. Four toothed plates 65 slide through the surface of the mounting ring 5 and are circumferentially distributed. A clamping plate 66 is fixedly connected to one end of the toothed plate 65 inside the mounting ring 5, and the clamping plate 66 is arc-shaped. A main gear 68 and a driven gear 67 are also included. The main gear 68 is rotatably connected to the mounting ring 5 by means of a support plate, and meshes with the toothed ring 61. The driven gear 67 is fixedly connected to one side of the main gear 68 and meshes with the toothed plate 65. A screw 64 is threadedly connected to one arm of the U-shaped frame 4. A movable plate 62 is fixedly connected to the arc surface of the toothed ring 61 inside the U-shaped frame 4, and one end of the screw 64 abuts against the movable plate 62. A spring 63 is fixedly connected to one side of the movable plate 62, and the other end of the spring 63 is fixedly connected to the U-shaped frame 4. When the mechanical mounting shaft needs to be fixed, the operator rotates the screw 64, which presses against the moving plate 62. The moving plate 62 rotates the gear ring 61, causing the spring 63 to deform. The gear ring 61 then rotates the main gear 68 and the driven gear 67 together. The driven gear 67 moves the gear plate 65 and the clamping plate 66. The four arc-shaped clamping plates 66 press against the mechanical mounting shaft, thus fixing it in place. When the mechanical mounting shaft needs to be disassembled, the operator rotates the screw 64 in the opposite direction, releasing the pressure on the moving plate 62. Under the restoring force of the spring 63, the moving plate 62 rotates in the opposite direction, and the clamping plates 66 release the pressure on the mechanical mounting shaft. Finally, the operator removes the mechanical mounting shaft. The fixing device 6 allows the mounting ring 5 to fix mechanical mounting shafts of different widths, improving the practicality of the mechanical adjustment frame.
[0031] Reference Figure 1-5 As shown, a rubber pad 69 is fixedly connected to one side of the clamping plate 66, and the size of the rubber pad 69 is adapted to the size of the clamping plate 66. The rubber pad 69 increases the friction between the clamping plate 66 and the mechanical mounting shaft, preventing slippage between them. Two symmetrical telescopic rods 610 are fixedly connected to one side of the clamping plate 66, with one end of each rod fixedly connected to the inside of the mounting ring 5. The telescopic rods 610 restrict the movement direction of the clamping plate 66, improving its stability. Two limiting rings 611 are fixedly connected to the outside of the mounting ring 5, located on either side of the toothed ring 61. The limiting rings 611 restrict the movement direction of the toothed ring 61, preventing it from sliding on the mounting ring 5.
[0032] Reference Figure 1-5As shown, the auxiliary device 7 is installed on the arc surface of the guide tube 2. The auxiliary device 7 includes an L-shaped plate 72, which is fixedly connected to the arc surface of the guide tube 2. Bolts 73 are threaded onto the surface of the L-shaped plate 72. A rectangular plate 71 is fixedly connected to the arc surface of the guide rod 3 at the location corresponding to the bolts 73. The rectangular plate 71 can be inserted into the interior of the guide tube 2. After the mounting ring 5 is moved to a suitable height, the operator rotates the bolts 73 on the L-shaped plate 72. The bolts 73 press against the rectangular plate 71 of the guide rod 3, thus fixing the guide rod 3. The auxiliary device 7 facilitates the operator's adjustment of the height of the mounting ring 5, thereby improving the practicality of the mechanical adjustment frame.
[0033] Reference Figure 1-5 As shown, a pull rope 74 is fixedly connected to one side of the bolt 73, with one end of the pull rope 74 fixedly connected to the L-shaped plate 72. The pull rope 74 limits the maximum displacement of the bolt 73, preventing it from falling off when not in use. Several anti-slip strips 75 are fixedly connected to one side of the rectangular plate 71, and these strips are linearly distributed. The anti-slip strips 75 increase the friction between the rectangular plate 71 and the bolt 73, improving the fixing effect of the bolt 73.
[0034] Working principle: When the mechanical mounting shaft needs to be installed, the operator moves the mechanical mounting shaft and inserts it into the mounting ring 5. The operator rotates the screw 64, which presses against the moving plate 62. The moving plate 62 rotates the gear ring 61, causing the spring 63 to deform. The gear ring 61 rotates together with the main gear 68 and the driven gear 67. The driven gear 67 moves the gear plate 65 and the clamping plate 66. The telescopic rod 610 on the clamping plate 66 restricts the direction of movement of the clamping plate 66. The four arc-shaped clamping plates 66, with the help of the rubber pads 69, press against the mechanical mounting shaft, thus fixing it. When the mechanical mounting shaft needs to be disassembled, the operator rotates the screw 64 in the opposite direction, releasing the pressure on the moving plate 62. At this time, under the action of the spring 63's return force, the moving plate 62 rotates in the opposite direction, and the clamping plate 66 releases the pressure on the mechanical mounting shaft. Finally, the operator removes the mechanical mounting shaft. The fixing device 6 allows the mounting ring 5 to fix mechanical mounting shafts of different widths, improving the practicality of the mechanical adjustment frame.
[0035] When adjusting the height of the mounting ring 5, the operator moves the mounting ring 5, which moves along with the guide rod 3 and the rectangular plate 71 in the guide tube 2. After the mounting ring 5 is moved to the appropriate height, the operator rotates the bolt 73 on the L-shaped plate 72. The bolt 73 presses against the anti-slip strip 75 on the rectangular plate 71, thus fixing the guide rod 3. The auxiliary device 7 facilitates the operator's adjustment of the height of the mounting ring 5, thereby improving the practicality of the mechanical adjustment frame.
